摘要:We describe the case of a child who, at her first episode of clinically evident acute otitis media, has developed a bilateral mastoiditis, though with unilateral simptomatology. The mastoiditis was complicated by the spontaneous drainage of the postauricular abscess in the subcutaneous tissue. According to the literature, we believe that the temporal bone computed tomography scan is the fundamental examination to properly define an anusual case of mastoiditis, plan adequate therapy (medical o surgical), and rule out other possible complications.
